WASH- BASIN.

SPECIFICATION forming part of Letters Patent No. 422,523, dated March 4, 1890.

Application filed February 14:, 1889. Serial No. 299,877. (No model.)

T0 to whom it mayconcern:

Be it known that I, EDWARD HAMMANN, of Brooklyn, in the county of Kings and State of New York, have invented an Improvement in Wash-Basins, of which the following is a specification.

In porcelain wash-basins as heretofore constructed a portion of the overflow-pipe has been made with the basin and the basin perforated at the entrance to the overflow-pipe, and the lead pipe connected to the overflowpipe has passed below the basin and been connected to the lead waste-pipe above the trap. These overflow-pipes frequently become foul, and because of their construction cannot be cleansed to advantage, as no direct access can be had to theintorior of said overflow-pipes.

The object of my invention is to so construct a wash-basin that access may be readily had to the interior of the overflow-pipe, in order that the same may be cleansed and be kept in as perfect condition as the basin itself.

In my improvement I construct the basin and the overflow=pipe of porcelain in one piece, the overflow-pipe or discharge extending outside the basin and from above the overflow-opening to the discharge-opening,

and the basin at the overflow-opening is cut away, so as to leave an entrance into the overflow-pipe, which is as large as the areaof the overflow-pipe itself, and this opening under allnormal conditions is covered bya perforated metal plate, which fits the same and is held to place by a head and screw-stem of metal engaging a hollow bolt and nut, which are secured to the porcelain body at the back of the overflow-pipe, and to the head of this screw-stem I connect a ring and the chain which passes to the basin plug or stopper, and I provide at the discharge-opening of the basin a flanged sleeve having a lateral opening and X-bars in the lower end, and which sleeve fits into the opening in the porcelain basin and extends through the base of the overflow-pipe, and to the lower screw-threaded end of this sleeve I attach a coupling-ring, above which is a washer, the ring and washer sealing against the under side of the porcelain. overflow-pipe and securing the sleeve in place, and the usual lead waste-pipe and trap are connected to the lower end of the coupling-ring in any desired manner.

In the drawings, Figure 1 is a vertical crosssection of the basin having my improvements. 5 5 Fig. 2 is a sectional plan in larger size at the line 00 a", of Fig. 1. Fig. 3 is a sectional plan in larger size at the line y y, and Fig. 4 is a sectional plan in larger size at the line 2 z of Fig. 1.

The porcelain basin a is of any desired shape, round or oval, and made therewith in one piece of porcelain is the overflow-pipe b, which extends from the upper edge of the basin a at the outside down and beneath the basin to the discharge-opening, and through the basin at c is formed an opening into such dischargepipe, which opening in area is fully equal to that of the discharge-pipe, and through the back wall of the discharge-pipe I make an opening in line with the center of the opening at c, and I secure a hollow bolt 61 and nut (1 within and filling this opening in the back wall, and which are permanent fixtures, the opening in the bolt (Z being screw-threaded.

I employ a perforated plate of metal 6, and the same covers the discharge-opening at c, and is secured in place against the face of the basin by the head f and screw-stem f, there being a conical head f on the head f, which engages the surface of the perforated plate a, the screwstem passing into the hollow bolt (1, and thus securing the perforated plate in place. An eye 9 is connected to the 8 5 head f, and the basin-chain g to said eye, and upon the lower end of said chain is fastened the basin plug or stopper h.

The porcelain basin a and overflow-pipe b are made with openings in which fit the flanged sleeve t', the end of which is screwthreaded, and near the lower end of which sleeve I form the usual X-bar z" for catching foreign substances in both the discharge and overflow water, and this flanged sleeve has a 5 lateral opening at 76 on the side next to the overflow-pipe above the X-b'ars i, and there is a lug at 4: upon the sleeve vi, which engages a notch at 5 in the porcelain basin, thus making it impossible to wrongly place the flanged 10o sleeve in position, the opening at it always coming on the side next to the overflow-pipe.

The porcelain body fits snugly around this sleeve '27, except at the opening 70, from which it tapers away to the sides of the overflowpipe. (See Figs. 3 and l.) This prevents foreign substances settling around the overflowpipe. The lower part of the flanged sleeve '1: is screw threaded, and the coupling-nut Z screws upon the same, and there is a washer 0 between the flange of the sleeve iand the basin and a washer m, that intervenes between the upper end of the coupling and the under surface of the porcelain overflow-pipe, to form tight joints as the sleeve z' is secured in place by the coupling-nut l. The flanged sleeve i and nut Z form a portion of the overflow-pipe.

Should the interior of the porcelain overflow-pipe need cleaning, it is only necessary to unscrew the headed stem f and remove it and the perforated plate 6 to gain access to the interior of the overflow-pipe, an d the op ening at c,when these parts are removed, is large enough for the introduction of a mop-cloth, by which the interior of the overflow-pipe can be cleansed, and, if desired, the sleeve i can read il y be removed from the basin by unscrewing the coupling Z, and thereby access to the lower part of the overflow-pipe for cleaning is facilitated, or the fingers can be inserted into the lower end of the overflow-pipe through the open upper end of the sleeve 2 as the X- bars t" are below the discharge-opening k and out of the way.

I am aware that before my invention an opening was made through the porcelain basin to provide access to the overflow-pipe and that the opening in the basin was closed by a perforated plate; but such plate was held in place bya bolt passing into an opening in the basin proper above the opening into the overflow-pipe, and such construction is different from my device, and I disclaim the same; and I am also aware that an instance exists wherein the discharge sleeve or pipe had openings into the overflow-pipe at opposite sides thereof; but in this case one of said openings formed a pocket or receptacle in which offensive matter could collect.

I claim as my invention- 1. The combination, with a porcelain basin a and overflow-pipe Z) in one piece and having an opening through the basin into the overflow-pipe and an opening in the back Wall of the overflow-pipe in line therewith, of a hollow bolt and nut introduced into and filling the openingin the back wall of the poreelain overflow-pipe, the perforated plate of metal 9, and a headed screw-stem passing through the perforated plate and engaging with the hollow bolt to hold the perforated plate in place, substantially as set forth.

2. The combinatiom-with a porcelain basin and overflow-pipe in one piece, and having an opening into the overflow-pipe and a perforated plate to cover the same and a dis-. charge opening in the lower portion, of a flanged sleeve 1', having a lateral opening at is on one side only, and around which sleeve the porcelain body fits snugly, except at the opening 70, and the coupling-nut I, screwed upon the lower end of the sleeve '5, whereby the lodgment of offensive matter around or in proximity to the sleeve 1' is prevented, substantially as set forth.

3. The combination, with a porcelain basin and overflow-pipe in one piece and having .an opening at the upper end into the over flowpipe and a discharge opening at the lower portion, of a flanged sleeve 1?, having a lateral opening at on one side only and coinciding with the lower portion of the overflow pipe, the X-bars 1' within the sleeve i'below the opening 7i; and the coupling Z for the waste-pipe, substantially as set forth.

Signed by me this 4th day of February, I). 1889.
